MACHINE FOR REMOVING SEED-FROM GRAIN.

SPECIFICATION forming part of Letters Patent No. 252,334, dated January 17, 1882. Application filed October 11, 1880: (ModeL) To all whom it may concern:

Be it known that we, DAVID TALMAGE and MARTIN L. FLowERs, residents of the city of New Orleans, parish of Orleans, and State of Louisiana, have invented a certain new and useful Improvement in Machines for Removing Seed from Grrain; and we do hereby declare the following to be a full, clear, and correct description of the same, reference being had to the annexed (lrawings, making a part of this specification. i

. The object of this invention, as its titlcindicates,is to separate and remove from rice or grain of any kind seed and other matter gathered therewith.

Ourinvention consists of a revolving screen, preferably hexagonal in form, and having its shell constructed of tubing, say, from threesixteenths to one-half of an inch in diameter, said tubing arranged at right angles to the supporting-shaft, and having their points of intersection strengthened by angle-strips running the whole length of the screen.

A further improvement consists in a means whereby one end of the shaft may be raised or lowered, so as to regulate the flow of-the grain through the screen, in combination with an oscillating journal-bearin g for the other end of the shaft.

On the accompanying drawings, Figure 1 represents a side elevation with cover raised so as to show more fully the nature of my invention. Fig. 2 is a cross-section through the line w m thereof, and Fig. 3 a view of an oscillating journal-box for the support of one end of the shaft.

A is a frame, the interior of which is provided with a casing, B, having a partition near one of its ends, as shown at O, and raised semicircularends, as atdd. In one of these endssay cl-a vertical slot is made, to permit of the passage as well as operation therein of the shaft 6 of the revolving screen D, one end of which is journaled in an oscillating box, f, and theothcr in a groove formed in the outer edge of a camor eccentric, i, which is keyed on a cross-shaft, g, and which is provided at one end with an operating-lever, k. The latter is held in any desired position by means of a pin on its inner side being brought in contact with one of a series of perforations formed in a segmental piece, I, that is secured to.one side of the frame, as shown. The grain is fed to the interior of the screen D through a pipe, K, which passes through one end of the casing, and has its lower end projecting into the said screen, as shown by dotted lines.

A cover, L, is hinged to one side of the frame, as shown at m, and which, if closed when the machine is in operation, will prevent dirt or dust arising from the same from escaping.

The trunnions a of the oscillating boxfop that all flat bodies, following the sides of the tubes, will readily find exit through the spaces between the same. The screen is made hexagonal in form, or any other shape except round, for the purpose of securing a tossing or jumping motion to the grain within the revolvin g screen, wherebya better separation of seed is secured. The tubes intersect to form a contin uous fluted sur-face throughout, and at their point of intersection are strengthened by the exterior angle-strips of metal, f, running the whole length of the screen.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A revolving screen having its shell constructed of tubing, arranged at right angles to the supporting-shaft and forming a cont-inuous fluted surface throughout the screen, and having their points of intersection strengthened by exterior angle'stripsrunning the whole In testimony whereof we have hereunto length of the screen as described, and for the signed our names. purpose set forth. v
